Phobia gets too upsetting with shoes (8)
I believe the answer is:
footwear
'shoes' is the definition.
(I've seen this before)
'phobia gets too upsetting with' is the wordplay.
'phobia' becomes 'fear' (I've seen this in another clue).
'gets' means one lot of letters goes inside another (gets can mean captures or absorbs).
'upsetting' shows that the letters should be reversed in order.
'with' becomes 'w' (abbreviation).
'too' written backwards gives 'oot'.
'oot'+'w'='ootw'
'fear' placed around 'ootw' is 'FOOTWEAR'.
(Other definitions for footwear that I've seen before include "Oxford maybe" , "boots, say" , "pumps, for example" , "Boots, shoes, slippers etc" , "Sandals and slippers" .)
